1.    U.S. Patent Serial Number: 08/546,745, filed October 23, 1995, titled "PROTECTION
      AGAINST NERVE CELL INJURY ASSOCIATED WITH NEURODEGENERATIVE
      DISORDERS." Inventor: Mark P. Mattson. This invention relates to novel therapeutic
      uses of staurosporine compounds to protect nerve cells from injury and death.

2.    U.S. Patent Serial Number: 08/560,946 and 08/094,637 (the parent), filed November 20,
      1995 and July 21, 1993 (the parent), titled "MULTICOMPARTMENT HARD
      CAPSULE WITH CONTROL RELEASE PROPERTIES." Inventors: George A.
      Digenis and Dagmar Noskova. The invention is a hard capsule formulated into a
      pharmaceutical delivery system which incorporates pharmacologically active components
      into three or more distinct compartments. The outer layer, for quick release, consists of
      pharmacologically active components coated on the outside of the capsule. The
      intermediate compartment contains a powder formulation of pharmacologically active
      components for intermediary speed release. The innermost compartment incorporates
      the pharmacologically active component in a multiparticulate form and is the slow release
      component of the capsule.
